Oh yes, even ran it with the cover off, made a mess, but it told me nothing. Everything is cycling as it should. no 'de-primed' lifters, meaning I cannot push them in with the rocker when valves are closed. Considering the oiling at the lifters, I assume it is not a stuck lifter, as I would not get any oil to the rocker arm, correct?
The rockers on these LA engines are oiled from the shafts, which get oiled through the block. (Magnums oil through the lifters and pushrods, but not LA's.) But it sure looks like plen-tee of oil.
If you are pushing on all the rockers to try to find a soft lifter, or other loose valvetrain part, you have to tun the engine for a few minutes to get oil in the lifters, stop the engine, and rotate the engine several times by hand and push on each rocker when its lifter is in the 'valve closed' position. (I.e., each lifter is on its cam lobe's base circle.) If you test like that, and all are hard, then you are good.
I got no audio on the video, and the video did not show the actual sound waves in the air.....
